Referring more specifically to the drawing the machine comprises a casing having supporting posts 2, and 2a "domesh'aped top 3 supported by the framefof the. casi11g,..t1he sides of the casing being provided with hinged doors 4:, anda sliding K1001 6. Tillie bottom of the casing is formed by a Iva-t l of semilindrical cross-section which is suitably. attached to. posts The wait, 1 receives the carrier which 's portst eyarn for movement the 36351111615111 the present em bodiment including a. horizontally jon'rn aled rotatable spider 7 "which as it rotates is adapted to. dip the yarn into the. a t.v

The hinged doors Flare each. provided with a con nterkbalanci ngWeight for keeping or pilot a SSiIIILlM pair-- the doors 0 rided with a spur gear,

pose the sliding door 6 is counter-balanced by a Weight 8 attached to the door by means of a cord 9 passing over suitable pulleys at the top of the casing.

The material adapted to be dyed by the machine is preferably in the form of skelns, as yarn skeins, which may be looped over pairs of the two series of yarn sticks 10 and 11 which are rotatably supported by rings 12 and 13, respectively, held in position by quadrantally disposed arms 14 of the spider 7. As the spider is rotated about its shaft 15, the yarn skeins supported on the yarn sticks 10 and 11 will thereby be carried below the surface of the liquid in the vat 1 and thereafter raised. out of the dye liquor in the at 1 or the action may be repeater. In order to hold the yarn stretched firmly on the sticks 10 and 11, the rings 12 and 13 are constructed to be rotatable with respect to each other and for this purpose ring 12 is fastened to the arms 14 whereas ring 13 is rotatively supported by the arms 14. Ring 13 is provided with a rack 16 mounted thereon, this rack meshing with a gear 17 mounted on a. shaft 18 which extends to a position adjacent one side of the casing. Shaft 18 is adapted to be rotated by means of a suitable worm gear 19 which inturn may be rotated by a crank 20 provided with a handle 21. Thus by rotating crank 20 the ring 13 may be rotated with respect to ring 12 thereby stretching taut the yarn skeins supported by and between respective pairs of the sticks 10 and 11 on the rings.

The spider 7 is composed of four arms 14 which are centrally disposed on the shaft 15 and support rings 12 and 13. The yarn sticks 10 extend from either side of the outer ring 12 being supported at one end only, the outer ends of these sticks being free. Similarly the yarn sticks 11 are supported at one end only in the inner ring 13. In order that the inner ring 13 may be rotated to the outer ring 12, certain of the yarn sticks are adapted to pass by arms 14 of the spider 7. To provide for this passage the inner ring 13 is constructed as shown in Fig. 8 wherein at the portion adjacent arms 14 the ring 13 is divided into two sections 22, each bearing laterally against the spider arm 14 at 23 and radially thereagainst at the surface designated 24. Intermediate adjacent arms of the supporting spider the opposite sections of the movable ring 18 may be supported in spaced position by means of a spacer ring 14 through which the spindle 36 of the yarn stick passes, as shown in Fig. 9.

Rotation of the spider or yarn carrier is effected by means of a. suitable electric motor 25 which voperatesthrough a pinion 26, and idler pinion 27, and a gear 28 to rotate a worm 29 meshing with a worm gear 30 mounted on a shaft 31. Shaft 31 is also proor driving gear 32,

which meshes with the teeth of a ring gear 33 mounted on the outer ring 12 of the spider. Thus by the power of the motor 25 transmitted through the reduction gearing above described the spider, or carrier, may be rotated, preferably at low speed, while in the vat to eflect the passage of the yarn through the dye liquor. The proper spaced relation between the shafts 31 and 15 is assured by a bar or link 84 pivotally connected to each of these shafts.

Adjacent their inner ends the yarn sticks on the outer ring 12 of the carrier have star wheels fixed to rotate with the sticks. In the present embodiment, and as shown in Fig. 4, the yarn sticks 10 are in the nature of spools fast on a supporting shaft 36,1rotatably mounted in bearings 37 and 38 of the outer ring 12, the star wheel being fast to the shaft 36 and being disposed between the bearings 87 and 38. The sticks 11 are carried on shaft 36 on the ring 13.

In order to facilitate the placing of the yarn skeins on the yarn sticks 10 and 11, and also their removal therefrom, and in order to subject the yarn to predetermined treatments, out of the dye liquor in the rat 1, the yarn carrier, or spider, may be bodily moved, or translated, out of the dye liquor in the Vat and the yarn sticks made to rotate under such conditions. The mechanism for translating the carrier into and out of the dye liquor in the vat 1 comprises a pair of link members 40 and 41 loosely engaging at one end with portions of the shaft l5 of the ear rier which shaft extends through the sides of the casing, the link members at their other ends being respectively connected with crank pins 42 and 43. Crank pin 43 is mounted on a crank 44, and crank pin 42 is mounted on a worm wheel 45, the crank and the worm wheel being keyed or suitably fastened at either end of the shaft 46 mounted on top of the casing and in the same angularrelation with respect'to shaft 46. lVorm wheel 4-5 is adapted to be rotated by a worm 47 and reduction gears 48, 49, 50 and 51 set in motion by an electric motor As the power is applied to the worm wheel 45 to lift the spider, or carrier, the shaft 15 is moved upwardly in guides 53 describing an arc of a circle about the shaft 31 as a center, since the link member 34 maintains a fixed distance between the two shafts. It will therefore be seen that the rotary motion of the spider, or carrier, may be continued regardless of the translatory motion produced by rotation of the worm gear 45.

The tripping mechanism for rotating the yarn sticks is illustrated in detail in Figs. 5, 6, and 7. The yarn stick tripping mechanism includes a trip comprising, in the present embodiment, a pair of pivotally supported fingers and 56 between which is rotatively supported a roller 57, there being an arm 58 connected to said fingers, The numeral 59 Indicates a trip 'tensloning sprin'g, one end of which 1s connected to the "arm 58 and the other "end to a lug test on a member of a trip positioning device.

The tripping "inecl'ianism is supported by a trip positioning device which, in the spe cific embodiment herein disclosed, is connected to maintain the trip in star wheel actuating position for ditiere'nt positions of translation of the yarn carrier, or spider. The trip positioning device may include a trip supporting radius bar 61 pivoted coaxially with the stationary axis of the driving gear 52, this radius bar, in the present embodiment, being pivot'ally connected to the driving shaft '31. The radius bar 61 is a strong rigid member preferably curving; as illustrated in Fig. 5 and provided with the lug 60 intermediate its ends. For supporting the'radius bar 61 in predetermined position there is provided a trip positioning yoke journaled or p'i'votal'ly connected on the shaft 15 ot 'the carrier. In the present embodiment this supporting yoke includes a transverse rod 62 passing through the forked arms 63 and or of the radius bar 61, and two arms and 66 disposed one on either side or the radius bar 61 and pivotally connected to the axis or shaft 15 'ot the carrier, the upper ends of the arms 66 receiving and supporting the transverse rod 62. The supporting arms and 66 are spaced apart sufficiently to permit the yarn sticks to clear the same as the carrier rotates.

It win he observed that the radius bar 61, the supporting arn'is "66. and the link 34 are related to each other as are the sides of a triangle. this relation being more apparent when the projection of these three elemen'ts on a plane surface is considered. Thus the radius bar 61 in conjunction with the supporting yoke and the link 34: provide, in'

eiiect, an articulated rigid frame journ'aled on the driving shaft 31. Likewise this frame, being pivota'lly connected to the shaft 15, moves synchronously in response to the translatory movement of the carrier or spider effected by the worm 4:7 and its operative connections to the shaft 15. The driving shaft 31 is supported in. suitable sta tionary bearings in the casing and is operatively connected through the gears 32 and 33 to etiect rotation of the carrier, or spider. And this operative connection between the gear 32 and the gear 33 is maintained though the trip positioning device he ro-- tated on the shaft 3'1. I

As the carrier of the spider rotates the star \vheels35 engage the trip roller 57 and the shock of the contact therebet'iv'eenis absorbed in the spring [59. Should the star wheels any reason tail to rotate, "the roller 57 will he torced asid 59 being adapted to yield and stances to permit the star Wheel to pass by. Upon release otthe roller 57 the arm 58 is prevented from being injured by the recoil due to the tension of the spring 59, by means ot a spring bumper device which comprises a U-shaped guide bolted to a stud 71 on the radius arm '61 and upon each arm of which there is provided a spring T2 pressingi' ..,;ainst across piece T3 lying in the path vice will support the tripping: mechanism in the path of the wheels of the yarn sticks and each star Wheel will be rotated so that part of the yarn in contact with the sticks will be moved into position "tree or contact with the sticks so as to readily ab sorb the dye liquor. Simultaneously with the rotation of the carrier, or between alternate rotations thereof, the motor 52 may be energized thereby causing the carrier to be translated and lifted from the dye liquor. The carrier may be held suspended above the dye liquor by arresting operation of the motor 52 or the motor may be permitted to continue to operate so as to alternately translate the carrier into and out of the dye liquor. yarn carrier with respect to the vat, it will be seen that the trip positioning device Will be actuated to maintain the tripping mechanism in stick rotating relation to the star Wheels. Furthermore it will be noted that the spring 59 which tensions the trip Wholly supported by the trip positioning device and in such manner that its tension is not atii'ected by the movement 01": the trip positioning device.

By reason of the yarn sticks being); rotat'ively connected to the carrier at one end only, the outer ends of the sticks being free these sticks may be mounted on the carrier in a permanent. manner, the skeins or yarn being readily applied. over the tree outer ends of these sticks. By operating the crank 20 the inner series of yarn sticks on the ring 13 maybe rotated relative to the outer series oi stick on the ring; 12 thus providing for adju 'ng thedistance between the respective pairs of sticks supporting the skeins and facilitating the application and removal of the sk'eins.

.Thus by the above construction are accom plished among others the object hereinbetore referred to.
